Answer:

31%

Step-by-step explanation:

To find the percent decrease, we can do (original - current) / original.

(1805 - 1240) / 1805 = 0.31 = 31%

Answer:

33.5% 50% 66.5% 150%

Step-by-step explanation:

So to calculate percentage after decreases you. Step 1) Get the percentage of the original number. If the percentage is an increase then add it to 100, if it is a decrease then subtract it from 100. Step 2) Divide the percentage by 100 to convert it to a decimal. Step 3) Divide the final number by the decimal to get back to the original number. Then you apply this formula to the equation to get the answer.

Is (-3, 2) a solution of 72 +9y > -3?
Alona [7]

Answer:

yes, (-3, 2) is a solution

Step-by-step explanation:

72 + 9y > - 3

9y > - 72 - 3

9y > - 75

y > - 75/9

y > - 25/3

y > - 8. (3)

y ∈ (-8.0(3) ; +oo)

(-3, 2) ⊂ (-8.0(3) ; +oo)

The graph of h(x) is shown below. Find h(-5) + h(5).
egoroff_w [7]

Answer:

9

Step-by-step explanation:

If you take a look at the graph, in order to find h(-5) you need to look at what the y intercept is when x=-5. In that case, when x = -5, y = 4 and so h(-5) = 4.

You do the same for h(5). Look at what y is when x equals 5. So h(5) = 5.

h(-5) + h(5) = (4) + (5) = 9

An airplane is flying at a speed of 500 mi/h at an altitude of one mile. The plane passes directly above a radar station at time
d1i1m1o1n [39]

Answer:

a)s=\sqrt{1+d^2}

b)d(t)=500t

c)s(t) =\sqrt{1+250000t^2}

Step-by-step explanation:

d = Horizontal distance

s = the distance between the plane and the radar station

The horizontal distance (d), the one mile altitude, and s form a right triangle.

So, use Pythagoras theorem

Hypotenuse^2=Perpendicular^2+Base^2

s^2=1^2+d^2

a) s=\sqrt{1+d^2}

(b) Express d as a function of the time t (in hours) that the plane has flown.

distance = speed \times time

d(t)=500t

(c) Use composition to express s as a function of t.

s(t) =\sqrt{1+d^2}

using b

s(t) =\sqrt{1+(500t)^2}\\s(t) =\sqrt{1+250000t^2}
